Patent Basics and General Information Concerning Patents: A Practical Guide
A patent is a federal grant giving an inventor the right to exclude others from making, using, selling, offering to sell, or importing a claimed invention for a limited time, in exchange for a full public disclosure of how the invention works. This guide is a comprehensive, cited reference on U.S. patent law for inventors, lawyers, founders, and anyone trying to understand how patents actually work. It walks through the constitutional and statutory framework; the three types of patents and their terms; the requirements for patentability (eligible subject matter and utility under Section 101, novelty under Section 102, nonobviousness under Section 103, and the disclosure rules of Section 112); ownership and inventorship; the application and prosecution process before the USPTO through Patent Center; publication, allowance, issuance, and maintenance; correction and post-grant proceedings before the PTAB; and the law of enforcement, defenses, and remedies. It incorporates the America Invents Act's first-inventor-to-file system and current practice, illustrates the doctrine with worked hypotheticals, and closes with topic-organized tables of leading cases and practical takeaways.
